Answer 1

You need to open module settings (Right click on your app module and select Open Module Settings or just select module and press ⌘ + ↓ on Mac)

And select compileSdk and buildTools to v20

Another way to do it is to open build.gradle file for the "app" module to change compileSdk and buildTools.
